JUSTUS A. TRAUI, OF NEW BRITAIN, CONNECTICUT.

PLANE.

SPECIFICATION forming part of Letters Patent No. 336,674, dated February 23, 1886.

Application filed January 29, 1385.

To all whom it nmy concern:

Be it known that I, Josros A. TRAUT, a citizen of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Attachments for Carpenters Plows, of which the following is a specification.

My improvement is especially designed for attachment to the plow patented to me March 4, 1873, No. 206,507, and March 11, 1884, No. 294,825, but it is also applicable to other plows or rabbet-planes.

In the accompanying drawings, Figure 1 is a side elevation of one of my said plows with my improvement properly applied there to. Fig. 2 is a view of the front'end of the same. Fig. 3 is a reverse plan view of the same. Fig. 4.- is a plan view of an attachment for said plow as adapted for a convex cutter. Fig. 5 is an end view of said attachment; and Fig. 6 is an end view of a part ofan ordinary plow-stock with one of my attachments applied thereto.

In my aforesaid plow the stock is in two parts, one of whichthe main partbears the handle and cutter, while the other part is adjustable on the gage-rods to and from the main part.

In the accompanying drawings only the main part of the stock A is shown, the other part having been removed, in order to apply my attachment.

B B designate the gage-rods secured to the stock A, and C the gage made adjustable on said rods.

D designates my attachment, which consists of an attachable and detachable bottom for the stock, having a throat, a, which forms a continuation of the throat and cutter seat in the main stock, and so coincides therewith that the cutter E, set and secured in said main stock, properly fits the throat in attachment D. Extending upwardly from the bottom of the attachment at one side is an upright, 1), upon which are mounted the sockets c, for receiving the respective gagerods, the same being provided with set-screws d or equivalent fastening mechanism for securing the attachment in place upon the stock.

In Figs. 1, 2, and 3 the attachment D is what carpenters term a hollow, and is de signed for use with a concave cutter whose width corresponds to the width of the hollow in the under side of the attachment.

Serial No. 154,307. (No model.)

Ihis cutter is placed within the main part of the stock, as shown, after which the attachment I is slipped upon the gage-rods up against the side edge of the cutter and secured in place. The attachment thus applied covers up the bottom of the stock proper, and if properly fitted the farther edge of the attachment will be in the same vertical plane as the farther side of the planestock, all as shown most clearly in Fig. 2. The attachment may be used either with or without the gage C, as may be desired.

.\Vhen it is desired to cut a molding of a different form, it isgonly necessary to provide an attachment whose under surface is of the desired configuration, and to fit it with a cutter of corresponding width and form.

In Figs. 4. and 5 Ihave shown an attachment, D, similar in all respects to the attachment D, except that it is rounding on its under face, and is designed for use with a convex cutter.

In Fig. (i I have represented a part of an ordinary plow, A, and an attachment, D for use upon the same in the manner before described. Asimilar form of attachment may be used with my patented plow, if desired, in which case it will be unnecessary to remove the minor part of the stock.

Planes having attachable and detachable bottoms are shown in several prior patents, and are therefore disclaimed.

I claim as my invention- The combination of the cutter, the main stock having cutter-holding mechanism, the gagerods B B, projecting laterally from one side of said stock, the attachable and detachable bottom having a throat which coincides with the cutter -seat of the main stock, and having also the upright 1), extending upward by the side of the main stock to said gagerods, sockets c 0, formed on said upright and adapted to receive said gage-rods, and fastening mechanism for holding the sockets in proper position on said rods, and thereby securing the attachable and detachable bottom in place, substantially as described, and for the purpose specified.
